JACOB HENRY BURLICII, OF NEW YORK, N. Y.

AUTOMATIC CLOSI NG DEVICE FOR CAN -SPOUTS.

SPECIFICATION forming part of Letters Patent No. 564,242, dated July 21,1896.

Application filed February 8 1 8 9 6 To all whom it may concern:

Be it known that I, JAcoB HENRY BUR- LICH, a citizen of the UnitedStates, residing at New York, in the county of New York and State of NewYork, have invented certain new and useful Improvements in AutomaticClosing Devices for Can-spouts; and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, and tofigures of reference marked thereon, which form a part of thisspecification.

My invention relates to an improvement in automatic closing devices forcan-spouts; and it consists in a perforated cap applied to the lower endof the discharge-spout, which is provided with a collar which fitsinside of the perforated cap, combined with a spring which surrounds thedischarge-spout, and is placed inside of the top of the perforated cap,a screw collar or cap which is applied to the screw-threadeddischarge-nozzle of the can or cask in which the fluid is placed, and acollar applied to the discharge-spout, and by means of which thedischarge-spout is operplied to the top of the can for that purpose, aswill be more fully described hereinafter. The object of my invention isto provide a device for automatically closing the discharge-spout of acan, and which remains normally closed and can only be opened whendirect pressure is applied to the dischargespout for the purpose ofraising it, and which immediately closes as soon as the spout isreleased, thus rendering it impossible for the closing device to be leftopen or for waste to take place in case the can is upset or turned at anangle.

In the accompanying drawings, Figure 1 is a perspective of a top of acan to which my invention is applied, and showing the closing deviceoperated by means of a lever. Fig. 2 is a vertical section of the same,taken through the closing device. Fig. 3 is a vertical section of theclosing device provided withacollar which is to be-operated by hand, theclosing device being shown opened. Fig. 4 is a Serial No. 578,576. (Nomodel.)

Fig. 5 is a discharge-spout for raising it.

Fig. 6 is perspective of the perforated cap. a detail;

1 represents a discharge-nozzle, which may be perfectly straight fromone end to the other, or have its upper end given any suitable curve orbend, and which spout is provided with the enlarged portion 2 at itslower end and the square shoulder 3, against which the lower end of thespring 4 is made to bear. This enlargedend of the spout fits snuglywithin the cap 5, which incloses its lower end and which cap is providedwith a series of openings 6 at its lower edge and abottom 7, which isprovided with a suitable valve or covering of leather, cork, or othermaterial 8, for the purpose of making a tight joint with the lower endof the discharge-spout 1, which bears or rests normally against it. Forthe purpose of makingatight joint between this cap 5 and thedischarge-spout, the enlarged portion of the spout may be provided witha packing of any suitable kind, or a packing may be placed upon the topof the shoulder 3, as may be desired. The manner of making a tight jointbetween the lower end of the discharge-spout 1 and the cap 5 isimmaterial, as this forms no special part of my invention, and for whichany suitable method of packing may be employed.

Between the shoulder 3 of the dischargespout and the screw-cap 9, whichis screwed upon the top of the discharge-spout 1 of the can, there isplaced a spiral spring 4; of suflicient strength to keep the bottom ofthe cap 5 pressed tightly against the lower end of the discharge-spout.In screwing this cap 9 into position upon the can the spring iscompressed with sufficient force to keep the lower end of thedischarge-spout pressed tightly against the bottom of the cap 5, andthus prevent leakage either when the can is upset or turned at an angleor when the can is inverted.

Applied to the discharge-spout, above the screw-threaded cap 9, eitherby frictional contact or by any mechanical fastening that may bedesired, is the flanged collar 12, by which the discharge-spout isoperated, and which rests normally against the top of the screwcap 9. Inorder to operate the dischargespout, it must be raised by means of thisflanged collar against the pressure of the spring 4, so as to withdrawthe lower end of the spout from the bottom of the cap 5, and thus leavethe oil free to flow through the opening 6 and out of thedischarge-spout. This upward pressure may be applied by means of a leveras shown in Fig. 1, or by hand, as may be desired. If a lever is to beused, the lower side of the flange will be made straight, whereas if thehand is to be used, the flange will be made wider and preferably curvedupward, as shown. The shape of this flange or the manner of applying itto the spout is a matter of small importance, as it forms no specialpart of this invention.

The great advantage of the construction here shown and describedconsists in the production of an automatic closing device through whichleakage can newer accidentally take place. The moment the pressure ofthe hand or the lever is relaxed the spring dcpresses the lower end ofthe discharge-spout and instantly shuts off the flow of liquid, and thisflow cannot be reestablished until the upward pressure is again removed.

As shown in Fig. 1, the lever is made in the form of two loops, theouter and larger one of which projects out under the handle 13 of thecan, where it is in the most convenient position to be taken hold of,while the outer and smaller loop is merely large enough to encircle thedischarge-spout and is provided with the two raised portions or flangeslel upon opposite sides, and which bear directly against the under sideof the flange upon the collar. Owing to these raised portions, but avery slight movement of the inner end of the lever is necessary to openthe discharge-spout to its full extent. The outer end of the smallerloop is turned downward, as shown, and rests solidly upon the top of thecan, which is provided with the shoulder 16 to prevent the lever fromhaving any endwise movement, the outer end of the smaller loop beingheld between this shoulder and the screw-cap. The lever is thusprevented from moving endwise and is held down upon the can by theflange upon the collar.

Having thus described my invention, I claim-- 1. In an automatic closingdevice, a discharge-spout having an endwise movement, a perforated capapplied to its lower end, a spring which keeps the lower end of thespout pressed downward, a screw-cap which is applied to the can,andagainst which the upper end of the spring bears, and a flange or handleapplied to the discharge-spout, substantially as shown.

2. In an automatic closing device for cans, the discharge-spout havingan enlarged lower end, a cap applied to the lower end of thedischargespout, and provided with openings through its lower edge and apacked bottom, combined with a spring which is applied to thedischarge-spout, a screw-cap through which the discharge-spout passes,and which is screwed upon the top of the can, and a flanged collarapplied to the dischargespout above the screw-threaded cap, and by meansof which the discharge-spout is lifted above the openings 6 in the capapplied to its lower end, substantially as described.

3. A can, provided with a handle, and a shoulder to one side of itsdischarge-nozzle, combined with a lever having its outer end to catchbehind the shoulder and to encircle the said nozzle, and provided withraised portions upon opposite sides of the nozzle and a handle portionwhich extends to or toward the handle upon the top of the can, combinedwith an automatic closing device, the spout of which has an endwisemovement, and is operated by the lever, substantially as shown anddescribed.

In testimony that I claim the invention set forth above I have hereuntoset my hand this 1st day of June, 1895.
